- the GtkCellRenderer (which our CellRenderer derives from) is not a
GtkWidget and therefor the 'get_display' method does not exist, we
fallback to the default display in that case [1]
- the get_rect method should return a Gdk.Rectangle now, see other
invokers
- check if event.mode is Gdk.CrossingMode.NORMAL to trigger a mouse
leave see 289787e8c6 for a similar
case
- todo: the Palette does not go away when the mouse leaves the
widget
